These walk-around photos were taken at the RAF Museum London in Hendon in 2019. They show an Airco DH.9A, serial F1010 — the only surviving example of the type in the world, and one of the most historically significant aircraft in the entire collection. Known affectionately as the "Ninak" (from the phonetic rendering of "nine-A"), the DH.9A was a complete redesign of the troubled DH.9, replacing its unreliable engine with the American 400hp Liberty V12 to produce an effective long-range strategic bomber. It entered service in June 1918 and after the war went on to form the backbone of the RAF's colonial policing force in Iraq and on the North West Frontier. Built by Westland Aircraft at Yeovil in 1918, F1010 was one of 18 aircraft presented to No. 110 Squadron by the Nizam of Hyderabad — each inscribed with his name and individually numbered, with F1010 becoming aircraft 12A rather than 13 out of superstition. Flying from Bettoncourt in France with the RAF's Independent Force, it took part in strategic bombing raids against German cities including Frankfurt and Cologne before being brought down during a raid on Kaiserslautern on 5 October 1918, its crew taken prisoner. The aircraft eventually ended up on display at the Deutsches Luftfahrt Sammlung in Berlin, where it survived an RAF bombing raid in 1943 thanks to museum staff who dragged it from the burning building. It was shipped east to Poland to avoid further damage and remained there until 1977, when it was exchanged for a Spitfire and brought to Cardington for full restoration. It has been on display at Hendon since May 1983.
